Organizers of San Francisco’s Folsom Street Fair have announced the dates for the next three installments of the annual fetish event.

The outdoor festival held in the South of Market neighborhood is returning to the last weekend of September in both 2013, the fair’s 30th anniversary year, and in 2015. It will be one weekend early in 2014.

This year’s fair was also moved up a week due to a scheduling conflict with Oracle OpenWorld. Because hotel rooms in the city are scarce during the tech confab, Folsom Street Events decided to change the date for the 2012 fair.

Looking to avoid a similar fate in 2013 during the fair’s milestone year, the nonprofit’s leaders worked with city officials and representatives from the Silicon Valley company to ensure the Folsom Street Fair could be held on its traditional date.

“Next year marks the 30th Folsom Street Fair, and we will revert to our ‘normal’ date on the last Sunday of the month. In 2014, we will move the date up a week again to avoid a similar conflict; but, for 2015, we are back to the last Sunday of the month again,” stated Demetri Moshoyannis, the nonprofit’s executive director.

For those who like to make their plans early, the Folsom Street Fair will be held Sunday, September 29, 2013; Sunday, September 21, 2014; and Sunday, September 27, 2015.

“We hope that this announcement will give everyone plenty of advance notice,” stated Jacob Richards, the outgoing president of Folsom Street Event’s board.

This year was not the first time that the fair’s date had been changed. According to the nonprofit, when the event was first launched it was timed to coincide with the autumnal equinox and its date varied.

Starting in 1993, however, the fair’s date was always the last Sunday in September. That tradition held until 2012.

“The decision to move the fair date this year was not taken lightly,” stated Richards. “When we have a conflict with SalesForce or Oracle Open World, the entire inventory of hotel rooms for the city is sold out. To avoid conflicts with other important events that bring visitors and revenue into San Francisco, we must look at the last two weekends in September.”
